The line of proposed new poles lie in agricultural land some 490m east of Kelham. A magnetic gradiometry survey was carried out with a Bartington Grad 601-2 fluxgate magnetometer. The path of the new overhead power line was divided into 30m2 grids and each grid was walked systematically in a zigzag pattern, taking readings every 0.25m in traverses 1m apart. The survey did not reveal any anomalies likely to relate archaeological features. The majority of features seen in the survey are likely to be modern in date or geological.
